These days they are busy with their own things, there is still a month from their plan, there is only one production line, but they may not be able to complete their respective tasks in the planned time, although the four people are not working together, but they are all in their own hurry to complete their own things.

Among the four people, the most work interaction is actually Qin Ming and Liu Xuan, both of them are responsible for the shell part of the "Exploration", in the manufacture of the indispensable discussion together, to find a shape that meets the dynamics and Qin Ming's requirements of the shell is quite difficult, in the original two experiments, the shape of the shell determined is not satisfactory, this time it is necessary to improve it, can save a little energy is a little.

In space, although there is still a lot of energy supply, but in some specific places, stones are not easy to find, long-term space travel, once there is no energy supply, it is simply a direct sentence to their death sentence, the waste of energy on the shell is more than imagined, so saving a little is enough for them to sustain the system for many days.

Of course, their energy is not only to use the energy of space itself, but also to reserve a little of their own, in case of any accidents, it can also be used urgently, in the vast space, maybe there are places that need a lot of energy, although their energy system can provide them with long-term energy, but a short period of energy requires a certain amount of time to accumulate, for their own safety, with energy is essential.

As for the energy they chose, it was something that they didn't dare to consider, that is, what Qin Ming was responsible for, that is, antimatter, the energy contained in this kind of thing is hard to imagine how big it is, under Qin Ming's research, in fact, they have already mastered a little bit of the method of using this thing at the beginning, although the conversion efficiency is not very large, it is relatively safe.

All preparations are still ongoing, this time it is not just a matter of the four of them, under Liu Xuan's request, Lao Gao is also limited in time, although Lao Gao is not in their team, but Lao Gao's current research is also quite useful to them, Liu Xuan also hopes to install this thing on their exploration ship.

However, these are not what Liu Xuan can say, this is not his technology, let alone his professional field, for him, this is not something that can be solved in a hurry, he can only hope that Lao Gao can complete his requirements. In addition, this technology is also very important for their company.

After the four of them left, once the company lacked innovation, it would definitely not be able to live for too long, Liu Xuan also hoped that this technology itself could bring their company more profits, which is still quite important for the long-term survival of a company, and Liu Xuan is also planning for the future.

In fact, Liu Xuan himself understands that once they go this time, they don't know when they will come back, and it is even very likely that they may not be able to come back, this technology itself is not human, he

We also don't know what's on the other side of the wormhole.

Take 10,000 steps back, even if their technology is not any problem, the energy is enough, they don't know how far they are from the earth, wormhole crossing, hundreds of light years are possible, if there is no wormhole over there, they can't come back at all, according to their technology, open up a new wormhole, just open up it is impossible, let alone locate the location on the other side of the wormhole.

Time is also a problem, in the universe, space and time itself are connected, and they don't know how long it takes to travel through a wormhole. The point is not that multiple sessions of time are spent in the wormhole, but that the wormhole distorts the time of multiple sessions. The wormhole itself is like a door, and the distance inside doesn't take long. The key is how long the time caused by the distortion of space is extended.

They also know the current situation of the earth, it is not an exaggeration to say that the earth civilization is a lighthouse in the universe, under the deliberate guidance of the gravitational waves of the alien civilization, there will also be many powerful enemies coming to the earth to fight, if it is the same level as the starfall civilization, they don't have to be afraid, but if it is so powerful with the mysterious planet civilization, if nothing else, the solar system when they come back is no longer the solar system they left.

These are all problems, but these problems are not a reason to deliberately block their progress, the first few times Liu Xuan could help the Federation just because of some accidents, take the second time, if it wasn't for the engineers who built them a mechanical body, if it weren't for their copied consciousness and chose to commit suicide, they wouldn't have entered the mysterious planet.

If there is another war like this, even if the four of them exist, there will be no other accidents, their own strength is weak, but not every time they can find each other's weaknesses to attack. The fundamental reason is that the earth's civilization is quite weak.

Now the earth civilization is at best the first level of civilization, the bottom of the entire universe, and now they can't even leave the solar system, of course, they all understand the method of evolution to the next level, what is missing now is the method of construction, you know, this hypothesis has been put forward for thousands of years.

The standard of the second-level civilization is to completely control all the energy of a star, and the Dyson sphere is the opportunity for human civilization to evolve again, and it is also the way, this thing is designed to use the energy of the star. At that time, the conjecture was to build a spherical thing around the sun, so that 100% of the energy emitted by the sun could be used, and if this thing was completed, human civilization would gain almost infinite energy. This is something that is necessary to evolve to a third-class civilization.

These are all later words, for Liu Xuan and the four of them, this is not their business, you know, the time they left this time must not be very short, if this time, human civilization does not evolve again, they may not be able to find the earth civilization when they come back.

Don't say anything else

If during this time, human civilization does not evolve, the attack of other civilizations will not be able to resist, the attack of the two civilizations is only the beginning, and definitely not the end, the current human civilization can no longer hide itself again, they have been exposed.

A month's time, soon more than half of the time, now the Star Ring Company, the four of them can fully master only one set of production lines, the last battle for the Federation, for human civilization The trauma is really quite serious, the interstellar battleships are almost all destroyed, even if there are only twenty left, it is almost scrapped, and it is not much different from the effort to build a new one if you want to completely repair it.

It is simply perfect for the current earth civilization to be used, which leads to the fact that it is only a month, the joint company will not be completely separated, and the best estimate is that it will take a year, and for the current situation, a year is still too long.

Liu Xuan, who has experienced two interstellar wars, actually understands very well that if it is really a battle, the battle between the two civilizations is cruel, and the time required is absolutely short, Liu Xuan is quite clear that the establishment of a civilization may take tens of thousands of years, but to destroy, it only takes a few short breaths, and their civilization is too fragile.

This time they passed through the wormhole, not so much to explore, not to mention to learn from the experience, this is a wormhole established by a super civilization, they can also boldly guess through this wormhole, this civilization is a rare peaceful race in the universe, perhaps, on the other side of the wormhole is their home, is the location of their civilization, in their civilization, maybe Liu Xuan and the four of them can get a shortcut to a higher level of human beings.

The current human civilization is still too young, the time of exposure is still too early, when their wings are not full, they are exposing themselves, causing them to hide not much time for peaceful development, time is quite important for them, since there is not much time to develop themselves, looking for a shortcut is also a good way to develop.

Human civilization still has a lot of opportunities, the universe itself is the same as human society, there is no desperate situation, as long as you still have time, then human civilization has the opportunity to continue to exist and develop, maybe at some point, human civilization has reached the peak of each civilization.

Of course, these are just beautiful reveries for now, after all, all this is based on the fact that they have not survived the attacks of many civilizations, and they cannot control time, so they can only do more things in a limited time, which may be the only chance for human civilization to continue to develop.

Everyone may understand this matter, there are not many people who can really do this, Liu Xuan and the four of them have a chance to count, but they have already set their sights on a more far-reaching place, which is full of dangers and challenges, and there are definitely a lot of opportunities and beauty. 、

A month's time, with the efforts of hundreds of them, borrowed

With a large number of advanced scientific and technological instruments, the "Discovery" is almost complete, all that remains is to install other unimportant equipment and carry out careful inspection, or it will not be long before this spacecraft will become the farthest man-made equipment in the history of human civilization.

In the past few days, the four of them finally have time to relax, and in a month's time, there are not many opportunities for them to meet, and even Liu Xuan and Qin Ming have changed. In the last battle, they lived in the Battlestar for a long time, and the facilities inside were quite complete, which also raised their skin to be quite white and delicate. But in the past month, most of them have been assembling thrusters and manufacturing shells at the rocket launch base, and the sun has also left its mark on their bodies, compared to a month ago, they are not a degree darker.

Especially Liu Xuan himself, his two tasks are outside, one is the thruster, and the other is the shell, which cannot be carried out indoors, Qin Ming's two tasks, one of them can still be carried out indoors. In addition, Liu Xuan is informal, when he is working, he always likes to take off all the clothes on his upper body and work bare-chested, and now, his upper body is a real bronze.

In the last few days, Liu Xuan still had his own ideas, he needed to meet Ringer, after all, they all needed to go on a long voyage, and even to cross the wormhole, without special permission, they had no way to avoid the defense system near the wormhole unconsciously, which required Ringer's special approval.

It is reasonable to say that Liu Xuan needs to go once, and Ringer is also their old friend, although he is now in an important position, he still needs to say goodbye to Ringer before leaving, which is also human nature, and Liu Xuan also understands.

Of course, Liu Xuan wanted to say goodbye to another person, but he didn't have the opportunity, it has been a long time since Li Ping left with his son at that time, and Liu Xuan has also hibernated many times for a long time, and now even if he is his own son, he is about the same age as himself.

Although they have been looking for them through various channels in the past few years, they are like evaporating from the world, no matter how much manpower and material resources Liu Xuan uses, they can't be found, Liu Xuan should say goodbye to them the most, but there is no chance, I have to say, this is Liu Xuan's biggest doubt before this trip.

At this time, Liu Xuan was sitting in front of Ringer, that is, in the Federal Parliament, Liu Xuan had already told Ringer about their plans and ideas, at first Ringer's reaction was normal, but in the end, Ringer himself couldn't suppress his true thoughts, in front of Liu Xuan, he couldn't suppress the shock in his heart, and the two big eyes stared at Liu Xuan tightly, trying to determine whether Liu Xuan was crazy.

But it has been five minutes since I finished talking just now, and Liu Xuan has been stared at by Ringer tightly for five minutes, but his expression is still quite calm, even

There was not a single wave to be seen, and Ringer could not see the true thoughts in his calm eyes.

"I have to say, your idea is really bold, but now we don't have too many opportunities, we can only pin our hopes on you, maybe you won't come back, but as long as you still confirm failure, we have hope." After staring at Liu Xuan tightly for a long time, Ringer let out a long breath and said to Liu Xuan.

Liu Xuan was already sitting quietly, and he didn't say anything, looking calmly ahead in his deep eyes, as if now his front was no longer Ringer, but the beauty of the depths of the universe.

"Since you have come to such a point, I have no reason to disagree, there is no problem with the special permit, I am here waiting for you to come back, before you come back, I promise that the earth civilization will exist. We may no longer exist when you return, but you must know that my spirit is with you. Ringer sat down slowly, his eyes determined and determined.

Liu Xuan still didn't say anything, just looked at Lin Ge slightly, nodded, Liu Xuan is like the saint described in the book at this time, although his own situation is not very good, but he can press his own state of mind, always believe, firmly believe that good things are about to happen.

Liu Xuan, who left the Federal Assembly, already had a special permit in his hand, and this matter was also regarded as a secret time of the Federal Assembly, and their departure was a secret of the entire Federal Assembly. In any case, they can safely and legally enter the wormhole, and whether they can safely reach the other side of the wormhole can only depend on themselves.

In the last few days, Liu Xuan still went to another place, which was full of Liu Xuan's fondest memories, where Liu Xuan also told Professor Ma, who had been sleeping for a long time, about his plan.

This is where his dream begins.

A month has just arrived, their equipment has been fully installed, all the inspections have been carried out, the rest is for them to carry out the inspections themselves, anyway, their plans are about to begin, this time, no one and nothing can stop them.

Today is the last day of the planning month, the four of them gathered in front of the "Exploration", a month of hard work, hundreds of people division of labor, the final result is this thing in front of them, this is definitely an epoch-making aircraft in the history of human civilization, but also the crystallization of all human science and technology.

A week ago, Lao Gao completed Liu Xuan's task and gave the finished product to Liu Xuan, and after making sure that there were no problems, Liu Xuan also specially installed this technology, at least before they left the solar system, they could communicate with the ground without delay.

Today's weather is very good, the sun is setting, the orange-red light hits the bright silver body of the "Explorer", it looks like a cloak on this crystallization of human technology, beautiful and solemn, there are no staff around, and now there are only themselves here

。

Tomorrow is about to leave, the four of them gathered here, did not say anything, just watched the sun set above the horizon very tacitly, silent, they all understood, if nothing else, this is the last sunset they see, from tomorrow they will be far away from the earth, it is definitely a lonely and empty place.

Silently watched the sunset, silently returned to their room, and people in history are the same, they are going to travel far away, they need to pack their things, the space designed by the "Discovery" is quite large, four people plus their things are definitely more than enough, they need to prepare their own necessary things.

The long night was still very quiet, and there would be a few cricket sounds from time to time. A few wanderers who have traveled far away will also leave their hometown tomorrow.
